The application can determine the sign-in path based on the user's email domain: if the domain belongs to a configured Entra tenant, the user is directed to that enterprise's SSO flow; otherwise it falls back to generic Microsoft OAuth sign-in.

UnverifiedWhen a customer only asks for employees to sign in with one click using Microsoft accounts, Microsoft OAuth alone is most likely sufficient; when the customer's security or IT team requires employees to sign in through the company identity system and have access managed centrally by it, that is the Entra SSO scenario.73% similarUnverifiedWhen connecting a Google or Microsoft account, the OAuth permission flow must be completed: the user logs in in the browser and checks the permitted access scopes (such as reading mail but not sending mail), and the provider returns a revocable token to OGAD. Reading and sending are two separate sets of permissions.70% similarUnverifiedIn multi-tenant mode, when the tenant placeholder in the authorization endpoint is set to common, Microsoft automatically directs the user to the sign-in page of their own tenant based on the email they enter, which is itself a tenant discovery mechanism provided by the platform.69% similarUnverifiedDomain routing built by the application side may be inconsistent with platform-level tenant discovery, because a user may sign in with a personal account email to an identity outside the enterprise tenant, so the mapping table should be based on verified domains and tenant IDs rather than inferred from the email string alone.68% similarUnverifiedCreating OAuth credentials with your own Google Cloud project means the Client ID and Client Secret are under your control, can be revoked and rotated at any time, and allow precise control over which mailboxes can pass testing.68% similar
